How to Use WhatsApp on Two Phones with the Same Number (2025 Update)

Introduction

Ever wished you could run WhatsApp on both your work and personal phones using the same number? Well, after years of frustration, WhatsApp finally delivered — as of April 2023, the “companion phone” feature lets you link one primary phone and one additional phone (plus up to three other devices like Web or Desktop) to the same WhatsApp account. That means your chats, media, statuses, and calls stay seamlessly synced and end‑to‑end encrypted across both phones.

Step-by-Step: How to Set It Up

Update both phones to the latest WhatsApp version.
On Phone A (primary), go to Settings → Linked Devices.
Select Link a Device.
On Phone B, install WhatsApp, then choose Connect as Companion Device.
Scan the QR code on Phone B using Phone A.
Voila! Chats sync and you’re ready to go.

Pretty easy, right? You can now reply to chats, view media, and even make calls on Phone B, even if your main phone is offline or out of battery.

What You Should Know

You need to re-link devices every 14 days if primary phone goes offline, or linked phones get automatically logged out.
Only one extra phone is supported; the rest must be desktop/browser apps.
You’ll see chat history from approximately the last year, but older media might not appear on Phone B.
Both phones share new media locally; but chat backups happen only on the primary device.
Not everyone has the feature yet- it’s gradually rolling out worldwide.

Smart Uses for Companion Phones

Business owners: Keep customer and personal conversations separate while using one number.
Families: Share a device for elder care or emergency use without switching accounts.
Multi‑device users: Follow WhatsApp from phone, tablet, and computer without relogging.

Frequently Asked Questions

1. I have two phones – what happens if I sign in on both?

Answer:

“Yes, as a companion device. But be careful! Don’t just login on the second device—when the button appears open the three‑dot menu and press connect”.
If done right, it stays linked. If not, you’ll break the connection on the primary phone and may even lose chat history.

2. How to use one WhatsApp account on two different devices?

Answer: Use the Linked Devices feature officially—no hacks needed. Just link Phone B as a companion device via QR scan.

3. Can one number be used on multiple phones?

Answer: Yes, but only one other phone can be linked officially. Other devices must be desktops or browsers.

4. Are there “tricky” workarounds to run on two phones?

Answer: Yes, some suggest using WhatsApp Web in a mobile browser (request desktop site)… but it’s unsupported, unreliable, and may get your account blocked.

5. I’m currently using it—what if phone A dies?

Answer: If your primary phone is offline for over 14 days, all linked devices get logged out  . Use backups and plan accordingly.

6. How to have 2 accounts on same number?

Answer: Not possible. WhatsApp allows one account per number. For multiple accounts, you need multiple numbers or data‑cloning hacks that violate policies.

7. Using WhatsApp Plus on two devices?

Answer: Not possible for same number. Mods like WhatsApp Plus aren’t compatible with the official server's multi-device system, and often lead to bans.

8. Other variants around using on two devices?

Answer: They all boil down to the same takeaway: official companion device = best/only safe way. Anything else is either not supported, risky, or temporary.

Final Take

Yes—you can use WhatsApp on two phones with the same number, securely and easily—but only through officially supported companion devices. It’s privacy-friendly, encrypted, and now rolling out globally. Steer clear of hacks or unstable setups to avoid annoying bans or data loss.
